FAN-BLOWER FOR T HRASHERS.

SPECIFICATION forming part of Letters Patent No. 234,356, dated November 9, 1880.

' Application filed March 10, 1880. (No model.)

To all whom it may concern:

Be it known that I, HADDOGK LINcoLN WARREN, of Alma, in the county of Ross and State of Ohio, have invented a new and useful Improvement in Fan-Blowers for Thrashers, of which the following is aspecification.

Figure 1 is a side elevation, partly in section, of the improvement, and Fig. 2 is a sectional elevation taken through the line :0 m, Fig. 1.

The object of this invention is to furnish fan-blowers for thrashers, by the use of which the feeders and band-cutters will be protected from the cloud of dust that constantly issues from the mouth of the machines.

Similar letters of reference indicate corresponding parts.

A is a horizontal frame attached near its rear side to the upper ends of two posts, B. The connection between the frame A and posts B is strengthened by inclined braces O, attached to the said posts and to the side bars of the said frame.

To the rear sides of the upper parts of the posts B are attached eyebolts D, to receive the hooks E, attached to the upper ends of the brace-posts F.

To the lower ends of the posts B F are attached clevises or loops G, to receive stakes for securing them to the ground.

In bearings in the middle partsof the side bars of the frame A revolves a shaft, H, to which are attached fans or wings I, to produce a blast of air. To one end of the fan-shaft H is attached a pulley, J, to receive the driving- 5 belt by which the fans are operated, and which receives motion from the thrasher.

The fans I are inelosed by a eylindricalcasing, K, which has an opening in its lowerforward side, through which the air is driven out 0 by the fans I. Air is drawn in to supply the blast through openings in the ends of the easing K, the size of which openings is regulated by slides L. The casing K is secured to the frame A by hooks M and staples N, or other 5 suitable means.

The machine is designed to be placed in the rear of the thrasher, and at such a distance from it as will leave the feeder room to do his work, and is designed to be so adjusted as to 50 deliver the blast of air upon the head and shoulders of the feeder, so as to drive the dust away from him, and at the same time keep him 0001.

Having thus fully described my invention, I 5 claim as new and desire to secure by Letters Patent The combination, with the fan-blower H I K, of the horizontal frame A, the upright posts 13, and the inclined brace-posts F, sub- 60 stantially as herein shown and described, whereby the fan-blower can be supported in the rear of a thrasher to deliver an air-blast upon the feeder, as set forth.

HADDOOK L. WARREN.
